The startup company RenewCO2 (Piscataway, N.J.; www.renewco2.com) has developed a catalyzed electrochemical process for selectively producing monoethylene glycol (MEG) in a single step using byproduct carbon dioxide from other processes as feedstock. MEG is important industrially because it is the…
Magnesium metal is important for several emerging potential sustainability-related applications, including carbon capture, low-carbon cement and energy storage. These potential applications are driving efforts to efficiently produce magnesium hydroxide, the raw material for manufacturing Mg metal. It is possible to…
An emerging electrolyzer technology for renewable hydrogen production is the anion-exchange membrane (AEM), which provides efficiency and cost benefits over other electrolyzer configurations. Until now, most AEM installations have been small, as the membrane assemblies’ size and durability limited the…
Catalysts by AM In late September, BASF SE (Ludwigshafen, Germany; www.basf.com) introduced X3D, a new additive-manufacturing (AM; 3D printing) technology for shaping catalysts. Catalysts produced with this technology feature an open structure, resulting in a reduction of the pressure drop…
Scientists at the U.S. Dept. of Energy’s Brookhaven National Laboratory (BNL; Upton, N.Y.; www.bnl.gov) and collaborators at Cold Spring Harbor Laboratory (CSHL; Laurel Hollow, N.Y.; www.cshl.edu) have genetically engineered a strain of duckweed (Lemna japonica) to produce high yields of…
Hollow silica particles (HSPs) are materials of interest for thermal insulation applications because of their very low thermal conductivity, but the particles pose health hazards and the powder is impractical to use, so scientists have been trying to incorporate HSPs…
Last month, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced NextGen Pelletizing — a visionary concept for the next generation of iron-ore pelletizing plants that strive to be carbon neutral and autonomous. According to the company, the combination of innovations —…
Polymer electrolyte membrane (PEM) electrolysis uses a membrane-electrode assembly (MEA) that integrates the electrolyte membrane and electrode (diagram). Large-scale hydrogen conversion of electricity requires a large number of MEAs, which is a drawback for scaleup, because the MEA relies on…
Batch reactors are widely used throughout the chemical process industries (CPI), and the basic design has not radically changed for many decades. Nevertheless, precise temperature control of batch processes continues to be a common problem. Now, a new design of…
Electrochemically reducing carbon dioxide to carbon monoxide offers a pathway to use CO2 as a feedstock, but the reaction is challenging because it requires catalyst molecules and dissolved CO2 to meet on the electrode surface. One approach to help this…
